That, and a good RAID controller with BBU cache will go a long way to relieving the pain of fsync.
even better than BBU cache is the newer 'flash backed caches'. works the same, but uses a supercap rather than a battery, and backs the cache up in a flashchip. typically 1GB cache on the newer SAS2 stuff. This way you don't need to replace the batteries in 3 years or whatever, or the complexities of having to move the raid card with the attached battery if the mainboard or chassis failed.
